SUPPORTING THE CARRIAGE-BODIES OF FIRE-ENGINES.

Specification of Letters Patent No. 25,628, dated October 4, 1859.

To all whom it may concern:

Be it known that we, LYSANDER BUTTON and ROBERT BLAKE, of lVaterford, in the county of Saratoga and State of New York, have invented an Improvement in Fire- Engines, and that the following is a full, clear, and exact description of the principle or character which distinguishes it from all other things before known and of the usual manner of making, modifying, and using the same, reference being had to the accompanying drawings, of which the figure is a perspective view of the engine box with one wheel removed, showing the improvement claimed.

Our invention consists in an improved mode of propping fire engines which are mounted on springs described as follows: Where fire engines are mounted on springs it is necessary while the engine is being worked to give it a firm support and for this purpose I provide suitable cams a, pivoted to the sides of the engine box 6, or frame work at a short distance above the axle c, and this cam is worked by lever (Z. The size and form of the cams are such that upon depressing the levers (Z, to the position indicated by red lines, the cams a, shall press firmly upon the axle c and thus throw the whole weight of the engine from off the springs and support it directly upon the axle making the engine perfectly steady during the working. After working, the cams are raised and the support of the engine thrown upon the springs.

What we claim is The propping of fire engines which are mounted upon springs by means ofcams a or mechanical equivalent thereof so arranged and operated, as by lever power to throw the weight of the engine from and upon the springs substantially in the manner and for the purposes set forth.
